Bill, I've seen Zodiacs with and without filler ribs.
I decided to use them for the looks. Without them, the elevator looks unfinished.

I completed my elevator just like the plans call for and it is not flimsy.
Stick to the plans is the advice I keep getting. I've seen some photos of
builders who filled in the holes and it looks nice, but nobody has convinced
me it helps in any way, so the choice is yours. Your time may be better
spent continuing with your progress than second-guessing the design. That's
my philosophy.

Standard fiberglass resins such as Hetron 127 (I believe that is the correct
number) are perfectly acceptable for gasoline, however the addititives in
the gas will dictate what resins are required.
I am currently working with a company that is using fiberglass for large
hydraulic cylinder barrels, so they can sense the position of the steel
piston in the barrel. There are a number of fiberglass companies that build
underground fiberglass storage tanks for gasoline.

DAVID !! think about every Glasair that has ever been built, ALL have "fiberglas
" tanks. Vinlyester resin is superior to almost anything when it comes to
resisting chemical invasion. I built a fiberglas tank for my boat almost 35
yrs ago from polyester resin which is much less resistant than vinylester and
no leaks as recent a 3 weeks ago. LOW&SLOW John

Hmmm -- interesting comment Frank. In reality, how many 4 place kits are
there to choose from that use all alu construction (preferably 'pop' rivets
as I'm still averse to buck-rivets), are simple to build and COMPLETE, will
carry 4 FULL SIZED people (and hopefully some luggage), are rugged enough to
use on backwoods strips (i.e. camping territory)....
I'd be interested in something like this in the future too, so I'm
interested in the results of your search. Right now the only prospects I
have on my list are the 640 and 801.

If I'm not mistaken, there's one more practical issue to consider. Water
conducts heat more efficiently when in liquid form, but if it 'boils'
locally (i.e. on an engine hot spot) then the resulting air bubble will not
conduct heat away.
So, the addition of the 'antifreeze' maintains the water in a liquid state
to prevent this.
Yes?

Yes that is a good point. It really comes down to what you need. In my case
I was looking for a relatively fast cross country cruiser with good altitude
performance that would suit my low hours as a pilot.
The fact of the pop rivets and simple build were not important in my
selection.
Hence when I found the thing was both not fast and not high I felt cheated.
I then found a lot of other benefits so I actually like the little HDS to
fly. Its interesting my original requirements are still very much big
factors that will affect my decision.
I was talking to a guy at the weekend who spent 17k on a pretty nice 4 place
Comanchi. If the performance claims for the 640 turn out as they did for the
HDS I would think something like this would work out more economically even
if I had to do owner assist maintenance.
Just a thought.

You can use vinyl esther resign and some epoxies
to lay up fiberglass tanks. It's done all the time.

Winston,
My header tank doesn't look like that. It's the standard plans-built tank,
and has barb fittings, 3 out the top, and 3 out the bottom. Looks like it
was set up for flexible fuel hoses to be connected. On the bottom, the
center outlet has a finger screen. The other 2 on the left and right point
downward. On the top, one outlet has a 90 degree elbow to the side, and the
other 2 point straight out toward the instrument panel. I know I can't use
all these outlets, so I was planning on plugging the unused ones, assuming I
retain the header tank.
Maybe one of the top outlets can accomodate a fuel level sender of some
type. And I thought about pumping fuel from the locker tanks into the bottom
outlets since there's more space to work there tan at the top of the tank.
Thanks for your help.
Dave

Maybe not. Actually the most efficient heat transfer in a
forced-convection system happens when "nucleate boiling" occurs. These
are small vapour bubbles that form on the hot surfaces and are then
pushed into the flowing coolant, where they collapse again. This way
the heat-of-vaporization is also removed from the hot surface, which is
significant. You are correct that if the coolant is allowed to boil so
much that it becomes mostly vapour instead of liquid, then you're in
trouble. I think if this were to occur in our systems you'd know it
because the pressure-relief cap would lift.

I'd be interested in hearing just how effective cabin heat is in anyone's
Zodiac. Seems like there's a lot of wind chill goin' on - could be hard to
keep up with unless someone uses a LOT of insulation and weather stripping
and seals off the flow from the rear fuselage into the cockpit....

Thanks Ray. I'm not an engines expert but I think this is similarly true for
all engines. They are usually only rated for full throttle/full rpm for a
few moments, then there is a max. cruise rpm setting below that which we are
allowed to use if we don't mind high fuel consumption.
My point was just that the great speeds that the Jabiru 3300 is finally
giving on the Zodiacs, only comes thanks to more 'ooomph' than Zenair
originally speculated -- I mean specified ;-).

Ensuring that the Center of Gravity is in the proper envelope at all times
in flight is critical to proper aircraft handling, as I'm sure you're aware.
If your aircraft is in the proper envelope (i.e. the Weight and Balance),
then that's as is should be and is a different issue than the nose-up
attitude in flight.
If your aircraft NEEDS 20lbs more weight in the tail to make the Weight and
Balance numbers work out better, then why not add some of this in the form
of a heavier battery? At least that way you're getting 'something' (more
cranking power, electrical power) for the weight as opposed to 20 lbs of
dead weight. (Someone else mentioned a tailskid as another idea). Does
Zenair have a specific weight limit for the tail-mounted battery? They
approved my rear battery rack installation but required me to 'beef it up'
with extrusions as opposed to my original idea of 'L's for the frame.
What is your aircraft's center of gravity now? Is it near the forward or
rearward limit?
Once you are sure that the CoG is always correct during a flight, (i.e full
fuel/minimum fuel; 1 small pilot/ 2 BIG pilot/passenger; No baggage/ lots of
baggage; Wing lockers?) ... then the next issue is the attitude at different
speeds, and the amount of control and trim authority you have.

Rotax Service Information 3 UL 97 D/E - R1 says, "NOTE: 50 % antifreeze
concentrate with anti-corrosion additives and
50 % water is recommended or an equivalent premixed
coolant. Sufficiently satisfactory results were achieved with
"BASF Glysantin Anticorrosion". This or an equivalent coolant
has to be used.
ATTENTION: Take note of the specifications from the antifreeze producer.
NOTE: If problems are encountered with boiling after engine stop,
increase percentage of antifreeze gradually.
In all cases, antifreeze to water ratios should not exceed the
antifreeze manufacturer's
recommendations. Exceeding the antifreeze manufacturers recommended
ratios can
lead to the formation of particulates in the coolant solution or
inadequate protection
against freezing.
ATTENTION: Particulate formation may be harmful to cooling system
components and may restrict coolant flow to and from
overflow bottle." Further, "Summary
* Use of a brand name of high quality antifreeze with corrosion
inhibiting additives
is recommended for ROTAX 912 and 914 engine series.
* Antifreeze used must be mixed with water as per recommendations of the
antifreeze producer to create a coolant solution suitable for the complete
temperature range of the engine and to provide adequate protection against
freezing.
* Coolant solution should be checked with a densimeter or glycol tester
to verify
protection level.
* Antifreeze to water ratio of 50 / 50 is required in ROTAX 912 and
ROTAX 914 series
engines."

My heater works great on the soob.
1972 ford pick up heater core with four computer muffin fans on the back. I
run two for low heat and all four for hi.
My heater core circulates water all the time. The radiated heat is not
noticable and avoids the complexity/weight of a heater valve and cable.
I positioned mine above the PX feet...don't want hot coolant on my feet

Composite Airplanes DO have epoxy and glass fuel tanks. If you check around
the gas in your car probably was pumped out of a fibre-glass tank at the
filling station as they don't rust and leak.
My Vari-Eze has a glass tank. Don't know who told you that they don't, but
they are wrong.

Cy, can you use auto gas with the fiberglass tanks? I know West makes a
fuel-proof epoxy, but I suspect they mean av-gas proof. Finding
anything that can withstand auto gas, especially alcohol-containing gas,
seems to be much more difficult.

as awesome as flying the Zodiac for the first time, but pretty close!

Well....I stand extremely well corrected. I can go
home now since I learned something new. Just wait
until I talk to Gary. So has anyone made any glass or
epoxy tanks for the XL?

There are all sorts of epoxy's that are formulated to
contain all types of fuels. They are formulated as fuel
tank liners, pipeline liners fuel tank sealants etc.

And what is in autogas that isn't in avgas? If you have a question about
West epoxy, ask them instead of making any assumption. I know I don't know.

Polyester is not very resistant to chemicals and the sort of thigs in Mogas
or Avgas. Vinylester is highly resistant and that's what I'm using in my
current build.

Seperate companies. I haven't taken them up on a good deal for a kit yet.
I will eventually build another, but with 2 flight schools, and a full time
job as a high school teacher, I won't be starting a new one soon.

Congratulations Phil. Did they give you a good deal, since you didn't take
them up on a good deal for a new kit?
Happy Flying,

Kind of a let down when you discover that your Guru isn't perfect isn't
it. At first Gary's word was gods message to me. Then I found a few
errors and later found out that he has to this day never built a
complete airplane. He is still a wise man in my eyes and knows a lot
more then I do , but now I seek a second opinion on a subject.
